Collection due process: lien and levy hearings

Collection due process is the taxpayer’s one statutory opportunity to have an independent officer look at a lien or a proposed levy before collection proceeds — and, uniquely among collection appeals, to take the result to the Tax Court. The deadlines are short and unforgiving, and the difference between meeting one and missing it is the difference between judicial review and none.

The rule

Levy. No levy may be made unless the Secretary has first notified the person in writing of the right to a hearing (IRC § 6330(a)(1)). The notice must be given in person, left at the dwelling or usual place of business, or sent by certified or registered mail with return receipt requested to the last known address, not less than 30 days before the first levy for that period. Only one such notice is required for the taxable period.

Lien. After filing a notice of federal tax lien, the Secretary must notify the person not more than five business days after the filing (IRC § 6320(a)(1), (2)). The right to request a hearing runs during the 30-day period beginning the day after that five-business-day period ends (IRC § 6320(a)(3)(B)).

The hearing. A written request stating the grounds produces a hearing before the IRS Independent Office of Appeals (IRC § 6330(b)(1)), conducted by an impartial officer, and the taxpayer is entitled to only one hearing for the taxable period (§ 6330(b)(2), (3)).

What may be raised. Any relevant issue relating to the unpaid tax or the proposed levy, expressly including appropriate spousal defenses, challenges to the appropriateness of collection actions, and offers of collection alternatives — a bond, substitution of other assets, an installment agreement, or an offer in compromise (IRC § 6330(c)(2)(A)). The underlying liability may be challenged only if the person did not receive a statutory notice of deficiency and did not otherwise have an opportunity to dispute it (§ 6330(c)(2)(B)).

Judicial review. Within 30 days of a determination, the person may petition the Tax Court, which has jurisdiction over the matter (IRC § 6330(d)(1)).

Suspension. The levy actions at issue and the periods of limitation under §§ 6502, 6531, and 6532 are suspended while the hearing and any appeals are pending, and no such period may expire before the 90th day after the final determination (IRC § 6330(e)(1)).

How it works in practice

The request is made on Form 12153, and the date is everything. A request filed within the statutory window produces a CDP hearing with Tax Court review at the end of it. A request filed late may still produce an equivalent hearing — the same Appeals officer, largely the same conversation — but no determination that the Tax Court can review, and without the suspension the statute attaches to a timely request.

The equivalent hearing has a deadline of its own: one year — for a lien, commencing the day after the end of the five-business-day period following the NFTL filing; for a levy, commencing the day after the date of the CDP noticeTY2026 (Reg. § 301.6320-1(i)(2) A-I7; Reg. § 301.6330-1(i)(2) A-I7). The two are deliberately different, and the regulations say so — the lien period is measured from the end of the five-business-day notice window, the levy period from the date of the notice itself. Appeals issues a decision letter rather than a notice of determination at the end of it (Reg. § 301.6330-1(i)(1)).

Because only one hearing is available per period, the grounds stated in the request matter. Appeals considers the verification that legal and administrative requirements were met, the issues the taxpayer raised, and whether the action balances efficient collection against the intrusiveness of the action. A representative who requests the hearing without stating collection alternatives, and without the financial information to support one, has spent the opportunity.

The liability bar in § 6330(c)(2)(B) is where cases are lost. If a notice of deficiency was received, or the taxpayer otherwise had a chance to dispute the liability, CDP is about how the IRS collects, not whether the tax is owed.

Five days, then thirty

The IRS files a notice of federal tax lien on 4 March and mails the lien notice on 9 March. The taxpayer's representative calendars a deadline 30 days from the filing date.

Analysis. Wrong start. Under IRC § 6320(a)(3)(B) the 30-day request period begins the day after the five-business-day notice window ends, not on the filing date. Calendaring from the filing date costs the client time and, if the request goes in late, converts a CDP hearing into an equivalent hearing with no route to the Tax Court.

The liability that could not be reopened

A client received a statutory notice of deficiency two years ago, did not petition, and the tax was assessed. Facing a levy notice, he wants the CDP hearing to establish that the deduction was proper all along.

Analysis. Section 6330(c)(2)(B) allows a challenge to the underlying liability only where the person did not receive a notice of deficiency and had no other opportunity to dispute it. He received one. The hearing can still be valuable — collection alternatives, spousal defenses, whether levy is appropriate — but the merits of the deduction are closed.

Late by a week

A levy notice is dated 2 April. The representative files Form 12153 on 9 May, six days after the 30-day period ended, and asks Appeals to treat it as timely because the client was in hospital.

Analysis. The request is late for CDP purposes. Appeals will normally offer an equivalent hearing, which gets the case in front of the same officer, but the outcome is a decision letter rather than a determination — no Tax Court petition under § 6330(d)(1), and none of the § 6330(e)(1) suspension. Where the merits need judicial review, the practical answer is to protect the deadline first and argue the hardship second.

Traps

The lien clock does not start on the filing date. Five business days to notify, then a 30-day request period beginning the day after that.

An equivalent hearing is not a CDP hearing. Same officer, no determination, no Tax Court, no statutory suspension.

The equivalent hearing window is one year, measured differently for lien and levy. From the end of the five-business-day period for a lien; from the notice date for a levy.

One hearing per period. The grounds stated in the request, and the financial information behind them, are the whole opportunity.

The underlying liability is usually off the table. Only available where no notice of deficiency was received and there was no other chance to dispute.

The suspension carries a floor. No affected period expires before the 90th day after the final determination, which can leave more collection time than a client expects.

How this has changed

Sections 6320 and 6330 were created by the IRS Restructuring and Reform Act of 1998 and applied to collection actions from January 1999; before that there was no statutory right to an independent hearing before levy or after a lien filing, and no judicial review of collection conduct. The most significant later change was jurisdictional: appeals from CDP determinations were once split between the Tax Court and the district courts depending on the underlying tax, and the Pension Protection Act of 2006 consolidated review in the Tax Court for determinations made after mid-October 2006, which is why § 6330(d)(1) now reads as a single route. Older material describing a district court alternative is out of date.

Exam focus

Learn the two timelines precisely: 30 days before the first levy for a levy notice, and for a lien, five business days to notify followed by a 30-day request window starting the day after. Know that the hearing is before the Independent Office of Appeals, that there is one per period, and that the underlying liability may be raised only where no notice of deficiency was received and no other opportunity existed. The 30-day Tax Court petition period after a determination is heavily tested, as is the CDP-versus-equivalent-hearing distinction.
